Nano bubble Solar pond aeration

Published on by in Technology

Dear colleagues can one of you recommend a cutting edge pond-aerator working on #solarenergy. It must be highly effective, no too expensive as it is for one of the least developed countries.
Fis-Ponds are around 2’500 square meters and max 2 meters deep. Temperature is close to 30 Celsius.
Thanks

  6. We have sized and provided all types of aeration equipment.  But I don't think you want nano bubbles if you con not provide electricity to the unit.  Nano Bubbles are used when you need a maximum amount of oxygen for digestion of a waste stream and are usually done under pressure in a side chamber so that the smallest bubbles are released into a recirculating water system for maximum oxygen saturation in the water stream that is released into the bottom of a reactor. That set up has a problem if this is a Fish pond (Fish-pond) because you will likely burn the fish gills.  (been there and done that with pure oxygen injection).

    If you are growing fish for production, I would suggest a bioaugmentation and/or bioremediation where the strains necessary for the fish waste can be digested by the proper bacteria.  We do that type of work.  These bacteria strains are specific for the waste digestion and reproduce every 15 minutes in optimal condition.  Periodic addition will keep the proper strains alive because when they run out of food, they die.  After about a month the evolution starts to take over and they change.  So the program is about once a week, or two. add some fresh cultures we have available in 2 oz throw packets.  The problem is the bacteria you need are aerobic. Thus, the request for aeration which would keep the natural aerobic bacteria growing, but probably not the correct type.

    We have kept rearing ponds for catfish and shrinp in continual production using this method, along with aeration with a bubbler and a compressor.  With the production of shrimp they were filling in the ponds with waste and the ponds had to be continually replaced until we went with the bio-bioaugmentation and/or bioremediation program. 

    If electricity is out,  the aeration can be set up with a windmill, or with solar. (We do both methods). But is is a larger bubble that does not require pressurization in a side tank   You just will not achieve a nano bubble without available electricity. 

    30 degrees Celsius is hot for a fish pond,  and 2 meters deep is shallow. You will need the bacteria if you are doing what I think you are doing.  With a lot of fish you can have a buildup of ammonia because the kidneys for fish do not make the full conversion to Nitrites/Nitrates. 

    The most use of bioaugmentation and/or  bioremediation has been for the digestion of industrial waste. During the last decade there has been more attention made for the reduction of ammonia buildup in the sewer digestion lagoons for smaller cities.  We have used the bacteria programs on ponds for 50 years to remove phosphate and nitrite/nitrate in ponds, with great success and lower algicide costs. 

    Good luck,  If we can help, let us know.  But specific information would be needed before making a recommendation.
